brown Italian sausage in a pan and remove it
add butter, spinach, minced garlic, heavy cream, tomato sauce, tomato paste, Parmesan cheese, and Italian seasoning, and season to taste with salt, pepper, and garlic powder
mix everything together well and let simmer
add cheese tortellini to the pan (still frozen), stir well, cover with a lid, and let cook for about 5 minutes until pasta is tender
add sausage to pasta and serve
I like topping it with more Parmesan cheese and some dried parsley!
